Method of labeling a package

ABSTRACT

A business form is provided which is particularly useful in shipping products where certain preprinted information can be provided and then individualized information is printed before the form is applied to a substrate. The form includes a face ply which has a pattern of adhesive applied to at least a portion of the inner face, and a release liner which includes a pattern of adhesive which exposes a portion of the release liner to direct adhesive contact to the face ply without intervening release coating to permanently adhere a part of the release liner to the face ply. The release liner has a surrounding protective border provided with release coating on the release face thereof and which is removed prior to application to the substrate, and a slip which remains with the form as applied to the substrate. The face ply includes lines of perforation defining a central portion. At least a part of the central portion is directly adhered by the adhesive to the slip without intervening release coating between the adhesive and the slip or the central portion. Individualized indicia, such as an address, may be printed on a label area of the top face of the central portion, while other individualized indicia, such as the content of a package, may be printed on the back face of the slip. Masking indicia is preferably provided on one of the inner face of the top ply or the release face of the release liner to inhibit viewing of the content indicia until the slip is removed from the package.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention broadly concerns a business form adapted for receivingvariable printing of information on both sides of the form an subsequentattachment to a substrate. In one particular usage, it is moreparticularly concerned with a business form which may be used as acombination address label and packing list for use in shipping articlesto a customer, and may include a return label portion.

2. Description of the Prior Art

The use of adhesive labels has become a growing segment of the businessforms industry with the emergence of catalog sales and other homeshopping vehicles. In addition to traditional wholesale shipments anddelivery to commercial accounts, consumers increasingly elect to makepurchases through telephone solicitations, through global computernetworks, and catalogs. Shippers have thus looked for methods ofincreasing the efficiency of the shipping and handling process.

A variety of different labels have heretofore been developed for use inshipping products. These labels increasingly use ready to applyadhesives such as pressure sensitive adhesives, rather than adhesiveswhich require wetting for activation, because of greater reliability ofadhesion and ease of application. Such ready-to-use adhesives typicallyrequire the use of a coated liner to prevent premature adhesion, theliner being discarded as waste. However, with the increased need forsecurity and efficiency in the shipping of packages, there has arisen aneed for improved business forms which will minimize the number and sizeof the sheets in the form, while providing for selective adhesion to theunderlying substrate and security in regard to the contents of thepackage, and also matches the shipping label and contents set forth onthe packing list.

SUMMARY OF THE INVENTION

These needs have largely been met by the duplex carton label/packinglist of the present invention. That is to say, the present inventionprovides a simple and economical business form which is easy to use,provides good adhesion to the underlying package or other substrate,limits waste, minimizes the number of sheets required in the form byperforming multiple functions and provides good security by limiting theability to view the packing list after application to the package. Aportion of the liner sheet also functions as a packing list, thuslimiting the number of plies necessary during manufacture and use.Moreover, the invention contemplates duplex printing of the liner in asingle pass through a printer, so that both the addressee informationand the packing list can be simultaneously printed on the form which isthen ready to use. Lines of weakness and separation are provided in theface ply and release liner to permit access by the recipient to desiredportions while the remainder stays affixed to the substrate. Adhesive isselectively applied in patterns between the face ply and the backing plyto provide good adhesion to the substrate without overextending into theareas serving as the packing list.

Broadly speaking, the present invention includes a face ply having a topface and an inner face and a release liner having a release face whichis pattern coated with silicone release liner to provide both coated anduncoated regions, and a printable back face. Adhesive, such as apressure-sensitive adhesive, is applied in a pattern between the plies.Preferably, the patterning of adhesive and silicone release coatingprovides areas between the face ply and release liner which are free ofboth silicone coating and adhesive, and some areas which have adhesiveonly to provide permanent adherence between the plies. Lines ofperforation or separation are preferably provided in the face ply todefine a central portion which may be further divided by perforationlines for use as an address label, return label, or pull tabs, and asurrounding border portion for adhering to the substrate, as well as atear strip for facilitating access to the central portion. The releaseliner may be provided with lines of perforation or separation to permitremoval of the release liner in a surrounding border for adherence tothe substrate, and a remaining packing label or list portion.

In preferred embodiments, the placement of the adhesive and siliconerelease can be varied to provide alternate configurations for the label.For example, in a first embodiment, the central label portion can be ofdouble thickness by providing adhesive but not silicone release betweenthe face ply and the release liner in the central label area. Thisyields a document suitable for filing and a more durable label which hasgreater tear resistance. In a second embodiment, the label portion maybe divided by lines of perforation or severance so that a doublethickness end tabs are provided, but single thickness address labels andreturn address labels are provided separate from a printable area on therelease liner. It is desirable that one of the inner face and releaseface be printed with ink so as to cover and visibly screen the printingappearing on the printable back face of the liner to prevent viewingafter application to the package without removal from the package.

The duplex carton label/packing list is easy to use. After preprintingeach of the face ply and release liner as desired, applying the siliconeliner and adhesive in the desired patterns, and making the appropriateperforation lines and lines of separation through perforation wheels ordie cutting, for example, the forms, which are preferably provided ascontinuous webs separated into individual forms by transverseperforations, are ready for local use. The user inserts the form into anordinary printer where no stylus is required. Most preferably, duplexprinters for simultaneously printing both the back face and top face areused, although the form permits sequential printing on top face and backface. Thus, computerized information can quickly be printed giving boththe recipient's address on the top face and the packing list on the backface. Either continuous feed or cut sheet versions can be used. Theperimeter portion of the release liner is removed and the remainder ofthe form is then applied to the package, with the address visible on thetop face. When the package arrives at the recipient, access is gained tothe packing list by placing a finger under one edge at a designatedlocation between the tear strip perforations and pulling on the tearstrip. The central portion is then pulled free through die cuts on therelease liner and perforations or other lines of weakness in the faceply, exposing the rear of the central portion as a packing list whilethe remainder of the form is adhered to the package.

As a result, high volumes of labels and packing lists can be generatedas a single form, as a single pass through a high-capacity duplexprinter can generate and print the necessary information. As no carbonpaper or other transfer media is employed to reprint the image ondifferent plys, no stylus is necessary and ink-jet, laser orthermal-transfer printers may be used. The form can be preprinted withthe exception of the individualized information to save time.Application of the address label and packing list to the package simplyrequires removal of the protective portion of the release liner,preferably located around the perimeter of the central area, andapplication to the package. This avoids the possibility that the packinglist and address label will be separated and misapplied to differentsubstrates. Upon receipt, the user grasps the tear strip which separatesfrom the backing to allow the central area to be torn free and exposingthe back face of the central area bearing the printing showing thecontents or other information to be revealed to the recipient. The labelis also tamper evident, such that the recipient can readily see tears tothe form if others have sought access to the information on the backface.

The principal benefits and uses of the present invention will be readilyapparent to those skilled in the art with reference to the followingdescription and the drawings appended hereto.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to the drawing, a composite address label and packing listform 20 particularly suited for local duplex printing is shown in FIG. 3and includes a face ply 22 and a release liner 24. The face ply 22 has atop face 26 and an inner face 28 oriented toward the release liner 24,and the release liner has a release face 30 oriented toward the face ply22 and a back face 32. Adhesive 34 and a silicone release coating 36 areapplied in patterns between the face ply 22 and the release liner 24 topermit selected attachment of the face ply to the release liner in someareas and to facilitate separation in others. Printing as well as linesof perforations or full severance by cutting are provided in certainareas of the face ply 22 and release liner 24 to provide the form 20hereof. Advantageously, some of the printing may be accomplished duringmanufacture, while other printing on the forms is individualized on aform-by-form basis.

It may be appreciated that the form 20 as shown in FIG. 3 is illustratedas a continuous web 38 of a connected series of forms 20 separated bycross-perforation lines 40 through both the face ply 22 and the releaseliner 24 into the individual forms 20. This construction permitsfan-folding of multiple forms and continuous feed during printing. Whenprovided as a continuous web 38, the forms 20 may initially include acontrol margin 42 along one or both longitudinal sides with feed strips44 and 46 defined by longitudinally extending lines of weakening 48 and50, the feed strips 44 and 46 being provided with tractor feed holes 52.However, the form 20 may also be provided in individual cut sheetsrather than as a continuous web of connected forms, dispensing with theneed for the feed strips 44.

In greater detail, form 20 includes a top margin 54, a bottom margin 56,and side margins 58 and 60. The face ply 22 includes a central portion62 for functioning as an address label 64 and a surrounding borderportion 66 positioned outboard of said central portion for attachment toa substrate such as a package, as shown in FIG. 8. As used herein,“inboard” relates directionally to the inner or central part of the forminwardly of the margins, while “outboard” refers directionally towardthe area more proximate the margins. The face ply 22 may includepreprinted indicia 68 including, for example, instruction indicia 70 forusing the form 20 and identifying indicia 72 for identifying the sender.Spaced apart first and second tear strip perforation lines 74 and 76 areprovided in the face ply 22 and extend from the top margin 54 almost tothe bottom margin 56 to provide therebetween a rear strip 78. Centralportion 62 is defined within the top ply by tear strip perforation line76 and by spaced-apart first and second transverse perforation lines 80and 82 generally parallel to the top and bottom margins and by labelperforation line 84 generally parallel to side margins 58 and 60. Borderportion 66 generally lies between the side margin 58 and tear strip 78,and between top margin 54, bottom margin 56, and side margin 60 andcentral portion 62.

Adhesive 54 34 is strategically applied in pattern between the face plyand the release liner. Preferably, the adhesive is a pressure sensitiveadhesive, and is applied in a border pattern 86 on the inner face 28 ofthe face ply 22 beneath the border portion 66, but preferably recessedabout 1 mm outwardly from the perforation lines 74, 80, 82 and 84 toresist adhesive migration and undesired attachment between the face ply22 and the release liner 24. The border adhesive pattern 86 is notcontinuous in that part of the border portion 66 on the inner face 28which is between tear strip perforation lines 74 and 76 except for apatch 88 of adhesive shown in FIG. 5 to facilitate access to the tearstrip 78 by the user but inhibit premature separation of the face ply 22from the release liner 24. A second, label adhesive pattern 90 isapplied to the inner face of ply 22 spaced interiorly of the perforationlines 76, 78, 80, 82 and 84 to provide an adhesive free ring 92. Apacking slip 94 is provided by a die-cut line of separation 96 in therelease liner. The adhesive-free ring preferably extends from about 1 mmoutwardly of perforation lines 78, 76, 80, 82 and 84 to about 1 mminside the line of separation 96, thus not only avoiding adhesive buildup on cutting members during manufacture but also aiding in separationof the label and packing slip from the remainder of the form 20. Theadhesive 34 may be applied within adhesive patterns 86 and 90 in acontinuous coating or as an intermittent coating to vary the amount ofadhesion desired.

Silicone release coating 36 is applied over the release face 30 of therelease liner in a release pattern 98. The release pattern 98 preferablyoverlies the protective border 100 of the release liner 24 and extendsslightly inboard of the line of separation 96. However, at least a partof the release face 30 interiorly within the line of separation 96 isnot included in the release pattern 98, whereby direct adhesiveconnection is provided between the face ply 22 and the release liner 24without any release coating therebetween. Preferably, this release-linerfree area 102 is recessed about 1 mm interiorly of the circumscribingline of separation so that release coating is provided on the protectiveborder 100 and across the line of separation 96. As a result, thecentral portion 62 providing an address label of the face ply 22 issecurely and substantially permanently bonded to the packing slip 94 ina two ply construction, with the remainder of the face ply 22 andrelease liner 24 outboard therefrom separable because any adhesive 34 onthe face ply 22 contacts the release coating 36 and does not directlycontact the release liner 24.

Preferably, the preprinted indicia 68 includes a printed masking area104 printed on the inner face 28, or alternatively on the release face30. The indicia printed on form 20 to provide the masking area 104 ismost preferably provided by ink or other visible coating which minimizesthe transparency and translucency of the area to which it is printed.The printed indicia is the masking area 104 may be either continuousprinting, as shown, or masking indicia as shown in U.S. Pat. No.5,376,048 (the disclosure of which is incorporated herein by reference)as masking printing 31 or masking indicia 48, and preferably covers morethan 50% of the surface area within the line of separation 96. That isto say, the actual ink coating is applied in a pattern or continuouscoverage in the masking area effectively prevents viewing through theface ply 22 to see any printing on the back face 32 of the release liner24.

In use, the form 20 is fed through a printer 106 as shown in FIGS. 1 and2 whereby individualized indicia 108 is printed on each form 20. Whilethe top face 26 may be printed and the form 20 removed and reversed topresent the base face 32, the form 20 is most efficiently employed usinga duplex printer 106 whereby in the same pass through the printer,individualized indicia in the form of address indicia 110 may be printedon the face ply 26 while at the same time content indicia 112 may beprinted on the back face 32. Because no transfer medium is employed, inkjet printers, laser printers, thermal printers or other non-stylusprinters may be employed as well as typewriters, dot matrix, daisy wheelor other stylus-type printers.

After the individualized indicia 108 is printed, the protective border100 is peeled away from the border portion 66 of the face ply 22 of form20 as shown in FIG. 5. This exposes the adhesive so that the form 20 maybe securely adhered to a substrate, such as a package 114 as shown inFIG. 8. FIG. 6 shows the form 20 as applied to the package in FIG. 8,and as may be seen in FIGS. 6 and 8, the address label 64 presenting theaddress indicia 110 is clearly visible, while the content indicia 112printed on the back face 32 is obscured from view. The construction andmethod of application substantially ensure a match between the intendedrecipient and list of contents, avoiding the possibility of mixing up anaddress label and a packing list because from the time of printing toapplication, the two are not separated or separable. This inhibits thelikelihood of incurring the substantial costs and onerous tasksassociated with mismatched labels and packages. Access to the back face32 is only possible by tearing the tear strip 78 along tear stripperforation lines 74 and 76, as shown in FIG. 7. By tearing the tearstrip 78 and then pulling up the central portion 62 along theperforation lines 80 and 82 as directed by the instruction indicia 70,the recipient gains access to the address label 64 bonded to the packingslip 94. The two plies of the bonded central portion 62 resist tearingand aid in maintaining the packing slip intact during tearing from theborder portion. The recipient then need only tear along the labelperforation line 84 to remove the packing slip 94 from the package 114,and thereby review the information on the back face 32 as shown in FIG.9. Tampering is evidenced by tearing of the perforations 74, 76, 80, 82,or 84, or around the border portion 66.

A second embodiment is shown as form 120 and is in many respects similarin construction and use to form 20. To the extent that elementsreferenced above with respect to form 20 are shown or described withrespect to form 120, the reference characters are the same. The form 120shown in FIG. 10 is illustrated as a cut-sheet form but could also beprovided as a continuous web of forms separated by cross-perforationlines and having feed strips as discussed with reference to form 20.

Form 120 has a face ply 122 and a release liner 124, wherein the faceply 122 has a surrounding margin 125 recessed interiorly of theperimeter 126 of the release liner 124 as shown in FIG. 10. Theprovision of a recessed area 128 provides ease of separation of theprotective border 100 during use of the form 120. Additionally, thecentral portion 130 includes not only the address label 64 but also pulltabs 132 and 134 and a return label 136, defined by pull tab perforationlines 138 and 140 and another release label perforation line 142 whichare parallel to label perforation line 84 and extend between transverseperforation lines 80 and 82.

Adhesive 34 is applied to the inner face 28 in an adhesive pattern 144as shown by the shaded area in FIG. 12. The adhesive pattern extendsinto the central portion but does not extend to the address label 64,that is, the area bounded by perforation lines 80, 82, 140 and 142, andpreferably about a 1 to 2 mm adhesive-free area is provided between anyadhesive and the perforation lines 80, 82, 84, 140, 142 and tear stripperforation lines 74 and 76. The masking area 104 is shown as reverseprinting indicia 143, i.e. the printing within the masking area createsindicia by the absence of ink, whereby both masking of the contentindicia 112 and additional preprinted instruction indicia 70a may beprovided on the face ply 122. The masking area 104 is shown as onlyextending across inner face of the address label 64, but it may beunderstood that the masking area could extend to the inner face of thereturn label 136, the pull tabs 132 and 134, or indeed the borderportion 66 if desired.

FIG. 13 shows the release pattern 146 of release coating 36 applied tothe release face 30 of the release liner 124, with the dotted linesshowing the margin and perforation lines of the face ply 122 forpurposes of comparison and to show the registry between the face ply 122and the release liner 124. The diagonal lines show the coverage of therelease pattern 146, which may also extend about 1 mm across the die cutline of separation 96 if desired to assist in the separation of thepacking slip 94 if the pattern of adhesive 144 is slightly misaligned,or outwardly to the perimeter of the release liner. As shown in FIG. 14,the back face 32 of the release liner 124 is provided withindividualized indicia 108, such as the content indicia 112 shown. Form120 permits the preprinted indicia 68 to include return addressidentifying indicia 72a and the additional preprinted instructionindicia 70a, as well as instruction indicia 70 and identifying indicia72 as shown with reference to form 20.

Form 120 is made similarly to form 20 in that the face ply 122 andrelease liner 124 are initially printed with the preprinted indicia 68,adhesive is applied in the desired pattern 144 to the inner face 28 andrelease coating 36 is applied in the desired release pattern 146 eitherto the release face 30 or to the inner face 28 after the adhesivepattern 144 has been applied, and the face ply 122 is mated in registryto the release liner 124. The continuous web 38 of the mated face ply122 and release liner 124 is then perforated through die cutting,perforation wheels or other conventional mechanisms, and the line ofseparation 96 is applied to the release liner 124 to provide the packingslip 94. As noted above, the continuous web 38 may be cross perforatedor individual forms 120 provided by cutting into separate cut sheets asshown in FIGS. 10, 12, 13 and 14. FIG. 10 shows the use of a controlnumber indicia 148 and a bar code indicia 150 to provide additional easeof internal accounting by the sender.

Form 120 is also used similarly to form 20. Individualized indicia 108including address indicia 110 and content indicia 112 are respectivelyprinted on the top face 26 and the back face 32 are printed by printer106 at the time of use, preferably by using computerized informationregarding the recipient. The protective border 100 is then peeled awayso that the form 120 may be adhesively secured to a substrate, such aspackage 114, with the top face 26 bearing the address label 64 withinstruction indicia 70 and identifying indicia 72 as well as addressindicia 110 visible, but content indicia on back face 32 hidden andmasked by masking area 104.

The recipient may grasp and pull the tear strip along tear stripperforation lines 74 and 76. Adhesive 34 directly contacts portions ofthe face ply 122 and release liner 124 within the pull tabs 132 and 133without intervention of a release coating to provide two plys andreinforcement when the central portion 130 including the packing slip 94are torn free from the border portion 66. However, in form 120, adhesivepattern 144 does not extend on the inner face 28 of the face ply 122within the address label 64, so that the address label 64 may beseparated along perforation lines 140 and 142 from the pull tabs 132 and134 and thus also from the packing slip 94. This enables the instructionindicia 70a provided by the reverse printing within the masking area 104to be visible to the recipient, thereby providing an additional printedsurface as shown in FIG. 12 while retaining the reinforcement providedby the two-ply pull tabs 132 and 134 and the masking function inhibitingviewing of the content indicia 112 until the packing slip 94 is tornfree.

Applicant has shown the form 20 as a continuous form with tractor feedstrips and form 120 as a cut-sheet form. The particular manner ofproduction is intended to illustrate examples, rather than limitationsas to the size or whether multiple forms or continuous forms areattached to one another. For example, form 20 is readily useful withoutthe tractor feed strips shown, either as a continuous form which may befan-folded or provided on rolls, or as a cut-sheet form. As a cut sheetform, for example, form elements 20A and 20B may be provided on a singlestandard-sized 8.5 inch by 11 inch sheet without the need for feedstrips 44 and 46 and separated by a cross-perforation line 20, althoughthe size of the sheet is not intended to be limiting. Similarly, form120 may be provided not as a single cut-sheet form, but also as acontinuous form as shown with respect to form 20, which may befan-folded or provided on a roll, or multiple forms 120 may be providedon a single sheet as described above.

Although preferred forms of the invention have been described above, itis to be recognized that such disclosure is by way of illustration only,and should not be utilized in a limiting sense in interrupting the scopeof the present invention. Obvious modifications to the exemplaryembodiments, as hereinabove set forth, could be readily made by thoseskilled in the art without departing from the spirit of the presentinvention. For example, the masking area 104 can be printed on eitherthe inner face of the top ply or the release face of the release liner,and may extend beyond the central portion and across the border portion.The adhesive may be applied in a continuous coating or a pattern coatingwithin the adhesive pattern depending on the degree of adhesion desired.It may also be appreciated that scoring of other weakening may be usedin place of perforation lines to provide lines of weakening, and thatsuch lines of weakening can be used in place of lines of separation.Additionally, the perforation lines need not be straight lines as shown,but can be arcuate or in other shapes as desired.
